ABSTRACT
Background: Multiple treatments have been used for the unicameral
bone cyst lesion, such as steroid application, multiple perforations, bone
curettages, partial resection and bone grafting. The purpose of this study
was to describe the evolution of children with unicameral bone cyst who
were treated with cryosurgery as coadjuvant therapy.
Methods: Cross-sectional descriptive study over the period between
January 2001 and December 2006. Twelve patients were studied and
treated at the Pediatric Orthopedics Department of the Pediatrics Hospital
at the Centro Médico Nacional Siglo XXI.
Results: Twelve patients were analyzed; all of them were treated with
curettage, cryotherapy and bone grafting. In 7 patients, the lesions were
located in the humerus (58.3 %), in 3 in the tibia (25 %), in 1 in the ilioischiopubic
branch (8.3 %), and in 1 in the clavicle (8.3 %). Follow-up
ranged from 12 to 36 months. Bone healing required 2 to 3 months after
the surgery; the response was complete in 9 (75 %) patients and partial
in 3 (25 %). Function was restored in all cases, without recurrences.
Conclusions: Cryosurgery as an adjuvant treatment and autologous
or homologous bone grafting prevented local recurrence of unicameral
bone cyst lesions, favored bone healing and allowed for a full range of
motion functionality without complications.
